Oct 24, 2008 · We build vacuum pumps for the composote industry, and we use any pump of choice (6 m3/h to 150 m3/h), switched with a vacuum switch. (We use a RT121 from Danfoss for that). This vacuum switch is adjustable (by hand, no fancy electronics) for any desired vacuum level, and also an adjustable hysteresis, which can be between 3 and 100 mbar.

Diffusion pump - Wikipedia

Diffusion pump - Wikipedia

Diffusion pumps use a high speed jet of vapor to direct gas molecules in the pump throat down into the bottom of the pump and out the exhaust. They were the first type of high vacuum pumps operating in the regime of free molecular flow, where the movement of the gas molecules can be better understood as diffusion than by conventional fluid dynamics. .
